Bryohumbertia P. de la Varde & Thér., Bull. Soc. Bot. France 86: 422. 1940.

Bryohumbertia contains three species with a pantropical distribution; the species given below is the only representative from the Neotropics. The leaf arrangement with whorls of larger spreading to erect-spreading leaves alternating with smaller internodal leaves that are erect to appressed, gives unmistakable characterization to Bryohumbertia (this feature is however found in a few species of Campylopus, most of which occur at higher elevations). In addition the following features aid in defining the genus: the costa, broadened at the base, the upper rectangular-rounded laminal cells, entire basal cell walls, well differentiated alar cells, ± erect seta, presence of an annulus, and smooth inner surface of peristome teeth. Bryohumbertia appears to be a weak segregate of Campylopus, differing by the erect, not cygneous seta, that is greater than 10 mm long.
